Both main characters are dragged into being different types of mutant humans. The powers in Tokyo Ghoul are more like a natural defense mechanism they are born with and in Ajin they are immortals and some can control a type of stand like in JoJo's Bizarre Adventure. Both shows are dark and dramatic, the key difference is that Ajin is a lot more cynical and Tokyo Ghoul likes to explore the interactions amongst Ghouls

Both stories have similar main characters that become hardened through their experiences. Kaneki is a ghoul, and Kei is an Ajin. Both of them became their respective species by deadly experiences. Ghouls possess superhuman strength, can only ingest humans, and have a kagune. Ajin are immortal, and they can form a black humanoid being that they can control.

Both have an MC become a ghoul or an Ajin.
Both MC used to be human and try to deny becoming what they have come
Both involve the MC fighting against other ghouls or Ajin
Both have the MC being hated by humanity
Both have a society of ghouls or Ajin
Both have ghouls and Ajin being both almost or completely immortal

-Both have an MC that is dragged into an unknown 'world' to them
-Neither one did anything wrong to deserve what they're put through
-Both MCs become the ones hunted by humans because of a deadly accident
-Organization vs Monsters
The main difference:
The MC in Ajin is a lot more clear-headed and is much more mentally and emotionally stronger, as opposed to the one from Tokyo Ghoul, who is less courageous and gives in to situations a bit easier.

Both main characters, who seem like innocent and kind teenage boys, are forced to hide from society because of their "monster" side. They both have a faithful, blonde-haired best friend. Both anime are of similar genres - psychological, action, supernatural.

Dark world where humans and and "monsters" live in the same society. ( Ajin (demi-humans) and ghouls). Both protagonists are living normal life, studying in school when accident happens and they find out that they're not humans anymore.
Both main characters are being hunted by the police forces and special ops.
Both MC's experience a lot of pain and are subjects of experiments and insane abuse.
Lots of action, violence, gore, fight between humanity and ajin/ghouls.
Psychological, questioning morals of what's good and bad/right or wrong, and humanity.
Good soundtracks

A constant shocking psychological game comes to mind of our protagonists in his discovery: stop human being. We can also see the strong conflict for his big difference, ghoul / ajin against humans, a large elite in search of these phenomena and our protagonists of one of these monsters. You will find peace again, that when it was considered human?

- MC have almost identical reveals or changes
- Something happens to MC later which makes op realize his fate (....Any guesses?)
- Story is very similar except
- Properties of the titular entity/black particle-y thing are similar to ghouls. There are few big dissimilarities though
- Blonde headstrong best friend who makes up for MC's lack of clear mind
- Worst Mother Ever perhaps?????
If you read TG Manga and if anime followed the plot perfectly then it would have been something similar to this minus the foreshadowing.

If you like the themes in Tokyo Ghoul, you'll really want to watch this anime. I was sucked in right from the beginning.
We all love a good opening song. It gives us the feel of the anime and gets us pumped. Everyone that has watched Tokyo Ghoul knows that opening just with the first sung note. So just like Tokyo Ghoul, Ajin has a very catchy, interesting opening song that gives you a feeling of anticipation and excitement. It's like that feeling of "yes, I want to see what this anime is about because this song is great!"
The main character in Ajin is relatable in his own way. It seems that it's normal to feel apathetic and uncaring because some of us lack the social cues necessary to be an empathetic person. The idea of being "cold and calculating" has become a normal thing in society. So, it's easy to feel like you can relate to the main character as he struggles with the lack of empathy many humans have.
Tokyo Ghoul, as well, has a main character that one can relate to. However, on an emotional level he is vastly different from Ajin's main character. He is an extremely empathetic/sympathetic individual that fights with the desire to eat flesh until he is faced with a terrible experience that leads him onto a darker path. Which is the opposite for Ajin's main character.
Kei, in Ajin, begins as nearly emotionless to an individual trying desperately to care for other human beings after experiencing unspeakable horrors. He goes from being a "jerk" as his sister calls him, to an individual that wants so badly to be compassionate and loving.
The action in both anime is amazing. There's never really a dull moment. It's really neat to see other worldly creatures go into hand to hand combat. And the fact that many characters in Ajin do not stay dead adds an interesting element into the mix.
And finally, one of the main reasons I love these anime is the reoccurring theme of moral ambiguity. There are horrible, inhumane things done to human-like creatures, Ajin and Ghouls alike. There is prejudice against the unknown. And let's be honest, these are things we face in the real world. Society has a habit of fearing the unknown and judging people that are seen as "different".
So, we find ourselves caught up in this ethical debate: should they die or live (Ghoul, Ajin, and humans alike). We want to fight against those wronging the main character but also struggle internally with whether it is right or wrong to actually kill a human being no matter how terrible they are.
All in all, this is an intriguing anime. I love these kind of dark, thought provoking anime. So if you're in the mood to question your morals, these anime are very good for that kind of thing. &nbspread more

Both main characters discovers they are quite different from the rest of the world. Their kind is also not acceptable in the society because they are considered as monsters. Both characters struggle to live in the world where they aren't accepted. Small similarities like the MCs name which starts with K, has a friend who has blonde hair and the leading/strong pursuer wears glasses and has a white colored hair. The rest of the similarities are easy to point out. They both also have the same theme.

the protagonist suddenly discover they are not human
similar concept of government wanting to hunt them down
they have a blonde loyal best friend
sato-san is like eto and likes to cause havoc on the city for fun

These two are very alike:
-Both MC's look alike
-Both MC's are weak at first
-Both MC's find out their a ghoul/ajin and is hard to accept it
-Ghouls and Ajins are alike in how they are not accepted in society
-Some of the characters are alike Kaneki/Kei Hide/Kaito Akihiro/Satou Arima/Tosaki

-Both of them have a main character who doesn't want to be this other species, but has no choice but to be it
-Both have the main characters mature over the series
-Both of them take place in a modern society
-In both, the main character has a friend who tries to help him

They both live in a world, where another specie that looks like a human, but has supernatural powers and doesn't die that easily.
Both main characters are going through a rapidly change, from being in the "human world" to have to get to know the "other world".
Both are very thrilling

- Both the main character is somebody with strange powers that make him an outcast.
- Both involves the same situation where the guy who is one of the hunted finds himself in a condition where he has to fight to survive.
- Both speaks about an human that become "non-human" and have to live in a world that try to kill him.
- The main characters of both anime become a being/monster and even though at first they are scared and confused, they overcome it and become pretty badass.
- Both are also action-packed and, while I liked Ajin more than Tokyo Ghoul in terms of Action ,fans of one will enjoy the other.&nbspread more

The struggle among human beings and "monsters" (ghoul or ajin). Principal characters dealing with a "non-sense" -at first, at least, for them– new identity, running away from danger (actually a prosecution of those who profess a lack of knowledge and fear of what is new) . Both animes depict a steady race for survival and an internal dialogue about what it means to be human.

It has a great plot,In both animes the main character is a boy which suddenly gets his humanity taken away. Both main characters are solitaires
Ajin main character is really intelligent and Cold-hearted .The anime fights look a little more realistic in Ajin,and they're not so overpowered has in Tokyo Ghoul.
The animation its kind a weird comparing to other animes but it does totally worth watching it.

Lots of blood, lots of drama
Not humanlike "people" that are seen as monsters
Good antagonists
interesting main character and main focus on the main characters methods (though to be warned the mains in these are completely different)
Awesome fights

Both main characters have to afront the idea that they aren't humans. They want to have peace in their lifes. They are going to try to find a way to live a normal life.
The difference between the main characters is that nagai (AJIN) is more manly than kaneki (TOKYO GHOUL).

Both have dark themes and are centred around the protagonist becoming something inhuman. There are a lot of other parallels, such as side characters acting similarly (strong female side character and a human best friend), but Ajin manages to hold its own as a series. It arguably does a lot of things better than Tokyo Ghoul, though many overlook its potential as a story and series for its unique animation, but the CGI in Ajin is high quality, and is among the top uses of CGI I've ever seen in anime.

These series are very similar. If you loved Tokyo Ghoul, I'm sure you'll love Ajin.
Both series have "Demi-Human" or Demonic Creatures in them, thus keeping a relatively dark atmosphere.This really gives both anime's good tones. The MC's both share physical and mental traits as well. Which makes it that much better to recommend. The dark/deep story's really make the stories that much better. Enough talk, go check out another great series, Ajin.

In Ajin and Tokyo Ghoul both protagonists are forced into a lifestyle where they become mutants. In Tokyo Ghoul, Ghouls are born with a weapon which they can activate at will, this works as a defensive weapon which protects them from their enemies and helps hunt. While in Ajin they're immortal beings whom can also control a weapon, this one is not connected with the user of the weapon and is used as an offensive weapon.
Ajin focuses on survival of a single person while Tokyo Ghoul on character development and fighting for eachother.

Both MC are dragged to become Unhuman that they didn't expect.
Similar Dark Themed Atmosphere, Also both have this psychological concept that will make the MC to a drastic mental change. Worth watching!

Both animes are intriguing, suspenseful, and action- packed. The biggest similarity between Tokyo Ghoul and Ajin is that both series explore in depth of what it means to be human, and the malice that humans beings show to beings that they don't view as human.

Both are about a group of people that are feared and hunted by society.
The main character is thrown into a life changing situation between the feared species and the humans.
Both have a a best friend that they depend on.

both series focus on main characters who both become something non-human, that they are afraid of/told to fear, and looked down upon by society, and both want to do something about it. the only difference is that kei nagai in "ajin" was *born* an ajin, while ken kaneki in "tokyo ghoul" *becomes* a ghoul by ghoul-organ transplantation.
both heavily discuss the idea of humanity as a whole and both characters' lives are turned around because of their newfound lives.
both characters are both kinda unreliable characters but definitely anti-heroes.
the only real difference between both series is that tokyo ghoul focuses more on how far it takes for the innocent to break, while ajin asks the question: what would you do if you were tortured for being who you are? and what makes, or qualifies, us as human?
overall, they both focus on humanity and what makes us human, as well as what drives us to the point of breaking. if you like psychological thrillers that will have you on the edge of your seats wanting more, then these are for you.&nbspread more

If you enjoyed the Anime of Tokyo Ghoul you will like this series.
Just like in Tokyo Ghoul Ajin has a new species the so called Ajin, who are superior than humans.
For me this series does everything right where the Anime version of Tokyo Ghoul failed.

I like both of them. Both series are good and unique in there own way but Ajin was in part inspired by Tokyou ghoul this is why Ajin reminds you of Tokyo Ghoul. The characters look the same, the main character has a monster inside them, the anime's a horror etc.

Both of these series deal with a main character rejected by society. As is the case with Kaneki, Kei is deemed as an unsightly being that needs to be "eradicated", or, in the words of the residents of Japan, "locked up and taken care of by the government". Both protagonists dance a fragile line between staying themselves and being what everyone else believes they are. Both are in hiding and both lose a bit of their humanity somewhere along the line. But unlike Tokyo Ghoul, Ajin doesn't completely screw over the second season (okay, maybe there's like one scene that could've been better). All in all, it's one of my favorite series out there. Don't let the animation throw you off - it actually grows on you! A must watch!&nbspread more

Ajin is the new Sei no Kakuritsu in my opinion because, the key about these two series is the suspense. Kei reminds me about Shinichi in some ways like :The poor main character who wants a normal life but, BOOM something comes on and change his entire life. Also,while Shinichi has Migi, Kei has his phantom or whatever it is.

"They are not human... right?"
All of a sudden an ordinary high school boy realizes he's not a normal human anymore, he begins to struggle trying to find a safe place in such a cruel world being despised by society.
Is he not a human, or are humans not humane enough?

Dark and cruel world. A fight between humans and parasytes/Ajin.
Both anime have a school boy who's pretty much innocent and naive, and finds himself to be the parasyte/ajin.
Lots of action, violence, gore, fight between humanity and ajin/ghouls.
Psychological, questioning morals of what's good and bad/right or wrong, and humanity.
Shinichi has Migi, Kei has IBM ( Invisible Black Matter) who fights and protect them.

-Are commonly associated with Tokyo Ghoul, but are much better.
-Have a dark theme
-Have a protagnist that is wimpy at first look, but can be serious when needed
-Protagonist is inhuman and hides his abilities

In both there are humans that need to hide because of supernatural stuff. The Ajin need to hide because of their abilities which the government wants to exploit and experiment on. In Kiseijuu the parasites are aliens that want to hide because of their plans and the main character is someone that kept control over his body and is all by himself like the main character in Ajin.
Both are involved/confronted with others of their "race" what want to harm humanity. And they don't want to work together with them. (Which means they need to hide from other humans and from others of their "race".)
Politics are involved in both. In Kiseijuu the parasits infiltrate political positions. In Ajin they Ajin try to influence the politics through fear and terrorism.&nbspread more

If you like Action, Horror, Psychological, Seinen... And of course Fantasy (Kiseijuu is Sci-Fi, while Ajin is Supernatural), you'll enjoy these animes.
There are big changes in high school students' lives, when they realize they aren't ordinary humans anymore. They're trying to live peacefully, while humans are hunting "monsters" (parasytes or demi-humans) and monsters are planing to take governance in their hands. But things aren't going as well as protagonists wanted to...
And both animes have similar atmosphere, so if you liked Kiseijuu: Sei no Kakuritsu, you should watch Ajin.

- Both deal with humans dealing with supernatural beings which are invisible to them and trying to exterminate them
- both MCs (Lucy in EL and Kei in Ajin) are cold-hearted killers in the sense that they protect themselves
- Both have gore
- Both MCs need to protect themselves from other members of their species
Differences
- Ajin has a slightly happier feel, less gore etc.
- EL has only female MCs which are in this different species, Ajin only has male
Both are dark and gloomy and if you like one you'll probably like the other, except Ajin's style may not be everyone's cup of tea but other than that they're both really good psychological-type anime.&nbspread more

Both protagonists are very smart and intellectual.
Both MC's have to escape police
same voice actors, lots of action, pretty intense and keeps you wanting more.
Morals of what's right or wrong/ good and bad.
Both anime shows how different characters can be when we see their reasons for acting one way or another.

I find it similar to Death Note as both series' got me, personally, hooked on anime. Death Note was my first anime, and it's the reason I started loving it. After a while, I drifted away from anime, and nothing really made me want to watch it again. So I decided to go out of my comfort zone and watch an anime that i'd never really heard of; and I'm so glad that I did. Ajin has really made me love anime in the way I used to again. Give it a go!

both are absolutely thrilling rides with a heavy plot and clever excitement. there's cat-and-mouse stuff going on here (L and light/kei's group and sato).
the pace of *ajin* isn't nearly as fast-paced as *death note.* both are very psychological and similar in vibe.
both shinigamis and IBM/black ghosts have the same concept.
*ajin* has a lot more action
strong police forces are involved, which serves as a heavy antagonist.
both protagonists are anti-heroes.
morals of what is good or bad.
both show how different the protagonists can be when we see the reasons for acting in such a way.

we have a guy who suddenly has a newfound perspective on life because he’s been granted a supernatural power. The main difference here is that Kei’s life immediately takes a downward turn because of his supernatural power, while Inuyashiki starts experiencing a more triumphant and glorious life. When one person is caught between a mysterious government agency and terrorists, it’s hard to expect any joy in life. The more subtle similarities deal with the action and the character relationships. In both, action scenes are characterized with brutal hits and pretty free-flowing CG. However, the intensity of bloodshed isn’t too high in either. There is a little more in Inuyashiki, but so far it is not gratuitous. Then there’s the way that Kei approaches Satou and tries to reign him in. This seems to be the route that Inuyashiki and Hiro are taking&nbspread more

What makes us want to live and what makes us so scared of dying? But if you could not die, what than? Would your views chance, would you still be scared of your own death, or would you face it again and again until you find the life you can be happy in.
Both of these psichological thrillers deal with these question in verry different situations and if you like the story of on you will surely like the other

-Both male MCs are physicaly weak but they are imoortals and can't die also they use every mean possible to win agaist their enemies no matter how dirty that is.Furthermore they are caught up in a power struggle.
-Both MCs live in a violent world where the weak dies and the strong survives.
-The enemies of both MCs are twisted and find amusement in fight furthermore they are manipulative and evil.

They both involve revival, fear, drama, uncertainty. People wanting to kill you. Not sure if someone is your ally or enemy. Both have a level of horror / gore (implied or otherwise). Both leave you really, really wanting to see the next episode. Both have a good focus on the nature, personality, and morality of various peoples/characters -- is someone being evil because they kill? Both start with a sort of mediocre high school male character, and both show subtle but minimal growth with the hint of future growth of the MC. Ajin is obviously more supernatural with a focus on humanity and violence, whereas Re Zero is more fantasy and over-the-top characters with a focus on the characters themselves, and especially the MC's perspective and mental workings. &nbspread more

Both have great and detailed animation that gives a lot to the atmosphere of anime and feeling. Lots of action, fights, deaths, blood and gore. Ajin has more of terrorism and killing, whilst Another has some detective horror story.

They both have that element of mystery and suspense which keeps you on the edge of your seat through both series. Another and Ajin both are pretty gruesome anime at times, but believe it when I say these types of anime are the best.

I consider these two anime the two best Thriller anime i've ever seen. And debating, Monster is probably the best Thriller anime existing.
They both have really smart MCs and deliver a story, which seems unbelievable hard for them. You could not think of a way for these characters, to solve their problems and the surrounding crimes. Both anime are dark, gloomy and real. At least they feel so.
Both anime have several plot twists, interesting characters and story lines and deep deep character development.

Dark, psychological, realistic animation, intense, lots of action.
Great character and story development.
Morals of society of what's right and wrong/ good and bad.
Some good plot twists showing us what we really didn't expected. We might hate some characters until we see their reasons of acting one way or another, and then you see it all differently.

Both anime feature an organization which experiments on superhuman beings in a massive government conspiracy. The main protagonist in both anime possesses superhuman powers and are now being hunted by an evil organization. They both have plenty of action, violence, blood and gore. If you like one, you should enjoy the other.

Dark world full of violence, gore, inhumane actions, horror.
Both anime makes you question what's good and bad, right or wrong.
Police forces try to stop criminals/ajin, because they're threat to society.

Moral ambiguity is a major theme in Ajin, which we see in Psycho-Pass. In Ajin, there are horrible, inhumane things done to "human-like creatures". There is prejudice against the unknown. And let's be honest, these are things we face in the real world. Society has a habit of fearing the unknown and judging people that are seen as "different", which is something that is brought up time and time again in Psycho-Pass as well.
So, we find ourselves caught up in this ethical debate: should they die or live (human and "monster" alike). We want to fight against those wronging the main character but also struggle internally with whether it is right or wrong to actually kill a human being no matter how terrible they are.
All in all, both anime are intriguing. They are both dark and discuss the various views of what is deemed ethical and good by society/a higher power in opposition to what other characters may see as morally sound. They make you question your own morals.
Each anime brings to the table something unique. Psycho-Pass is a psychologically based anime in which people are deemed as "latent criminals". This means, if someone is viewed by the Sibyl System (the governing power) as a possible threat to society, they are tossed into rehab or worse, some end up in holding facilities for the remainder of their lives. From the beginning, these people are seen as criminals without actually committing a crime because they are "different".
Similarly, in Ajin people that are deemed different are turned into test subjects. Society sees Ajin as something like scum. And the government uses them as their play thing because who cares about a monster, right?
These anime are horror. There is a lot of blood, gore, and deaths. There is always a lot of action. If you want standard animation, I would recommend Psycho-Pass because Ajin is very CGI. However, both are very interesting in their own right.&nbspread more

Are they human? Not exactly, in Ajin, Nagai Kei is an Ajin or Demi-Humans if you prefer. Ajin's look like normal humans on the outside, but are actually immortal and have the ability to summon an IBM (Invisible Black Matter), which cannot be seen by the naked eye. While in Kabaneri of the Iron Fortress, Ikoma is a Kabaneri, something inbertween a human and a kabane. If you are suspected or confirmed to be a Kabane or Ajin you will try to be captured by someone, and eventually turned in to the government. The government will kill Ajins over and over, while in Kabaneri of the Iron Fortress they will just make you to use the suicide bag. Each show also has an old friend of the main character who helps them, even after everyone else has declared them a threat to the rest of the society. Each show has a unique art style. They are both animated by up and coming studios, Polygon Pictures (Ajin), Wit Studio (Kabaneri of the Iron Fortress).&nbspread more

thts meaning the genre almost same,....
Nagano Kei in anime AJIN is not a human......maybe seems like a immortal human, just like Ikoma(The main character in Koutetsujou no Kabaneri), he is half human half kabane(Kabaneri).
Both of the main character has a special power, and they'r've a supporter character tht always help them......
This anime is vr awesome, cool, etc

Both characters were living somewhat perfect lives, until they were just dealt a bad hand, albeit one could say a well deserved hand, and now they have to adapt to what they were given in order to survive daily.
- Ajin involves a methodically thinking student who is thrown into a world of "terrorism and misunderstandings."
- Youjo Senki involves a methodically thinking office-worker who is thrown into a "magical WW1-esque era."

Dark world where humans and and "monsters" live in the same society. ( Ajin (demi-humans) and ghouls). Both protagonists are living normal life, studying in school when accident happens and they find out that they're not humans anymore.
Both main characters are being hunted by the police forces and special ops.
Both MC's experience a lot of pain and are subjects of experiments and insane abuse.
Lots of action, violence, gore, fight between humanity and ajin/ghouls.
Psychological, questioning morals of what's good and bad/right or wrong, and humanity.

I don't like anime with silly characters where decisions don't really make sense and their thinking seems random. Both these anime have intelligent characters, where you can only be pleasantly impressed with their decisions and thinking patterns. I guess both have a psychological aspect. They're not at all similar in terms of the plot.
It's weird to say this since they both involve supernatural elements to the plot (time travel for Boku Dake, and Ajin creatures in Ajin), but they're both very realistic in a sense, I guess because of the way the characters respond to situations and the internal consistency. You won't feel like you're being treated like an idiot by these anime. 9/10 or 10/10 for both&nbspread more

The characters and the general atmosphere are quite similar.The characters are sometimes cruel or the protagonist isn't like your typical protagonist and can be cold hearted.Also the dark creatures in Ajin are similar to the headless rider in Durarara.Plus they are mystery and supernatural genres.

Two and very very different anime, yet they have some things in common.
Detailed and great art style ( even though ajin has cgi, it helps to create a darker atmoshpere and makes anime even better)
Soundtracks are used well to help people to get in touched with characters and anime. Make it intense or easy and enjoyable.
Also same voice actors

Both shows contain MCs who have become a sort of supernatural creature. While Deadman Wonderland focuses on the protagonist after being caught, Ajin focuses on the protagonist's escape. Ain is very similar to Deadman Wonderland and vice versa.

Gokukoku no Brynhildr and Ajin deal with humans who have gained supernatural powers. Both protagonists and their friends are hiding from scientists who want to run tests on them. Both contain gore, psychological and horror elements.

both are a "Immortal Human vs Mortal Human" series
both character appearance are similar (Look at Izumi from Ajin and Ennis from Baccano!)
But beside it, Baccano! Use Alchemy And Ajin have some science theory / reaction for explain what is the Immortals are..

Ajin and Big Order have a lot of similarities. To start, the main protagonist isn't exactly human. In Ajin he is an Ajin, which is a human who cannot die. While in Big Order, the main character is an Order user, his Order basically destroys everything around him. Each protagonist has a mummy like creature he can summon. The female main character in Big Order also, is immortal and regenerates after she is killed. In each series the protagonist has a younger sister who is in a hospital. To finish, each protagonist is being hunted by a group of people.

This movie BLAME! without a doubt is amazing. The similar between Ajin and Blame! is breathtaking events happening through out the movie and the series, It gets you heart raceing of what is going to happen next.
1. Amazing Animation
2. Amazing Cast
3. Amazing Story
I recommend to watch both of these anime. The action is amazing and everything else is to. Im not putting to much details but its amazing!!!

Nakano Kou from Ajin reminds me a lot of Shirou from FSN. Even though Ajin 1st season is mostly about Nagai Kei, Kou has a more significant role in the 2nd season. Kou and Shirou are both redheads with similar hairstyles; and wouldn't mind risking their own lives to save others. Luckily for them they are both near immortal (Many characters from Ajin because they are an ajin, Shirou because of some kind of plot device).
Both anime have plenty of gore and epic action scenes. A major difference is that Ajin has more realistic characters IMO, while in FSN the characters are mostly archetypes (tsundere etc.). &nbspread more

Do you want to become immortal? Maybe you should first watch Ajin and Mnemosyne and reconsider. In both anime the main characters as well as some of the antagonists are immortal; and in both series these immortals will have to suffer a great deal because of their immortality; such as being used as living test subjects for the weapon industry or used to harvest an infinite amount of organs. Both anime have plenty of action and some gore...and they might make you reconsider whether immortality would be a blessing or a curse.

Both anime are full of action with dark, horror and psychological elements in them. Both titles have characters with superhuman powers and feature the main protagonist in both titles being hunted by other humans. They are both very violent as well. If you like one, you should probably like the other.

Both anime are dark supernatural anime. The main protagonist (Yakumo Fuuji in 3x3 Eyes and Kei Nagai in Ajin) in both titles are immortal beings that can not die. The main protagonist in both titles got hurt in similar a deadly accident and end up finding out that they are immortal. The main protagonist both have a friend on their side to help them out. Both titles have action, violence, blood and gore with a very dark and gritty atmosphere. If you enjoyed one, you will enjoy the other.

Both anime deal with the main protagonist trying to be exterminated by scientists and are being hunted by an evil organization. The main character in both anime are considered to be a danger to other people and has a companion to help them escape from evil. They are also both quite action-packed and violent as well. If you like one, you will enjoy the other.

Searching for people who keep coming back to life just like in Ajin? Well, Mermaid Forest is just like that. In Mermaid Forest, those who eat mermaid flesh become immortal. The protagonist, who is 500 year old, search for a way to turn back into a normal human again. The plot may not sound so similar to Ajin, but whenever some character dies and comes back to life I simply can't think about anything else. It really gives a lot of Ajin vibes.

- Both main characters are being chased by the government.
- They have been treated in a very cruel and unjust way at some point.
- They're not exactly positive characters.
- Both of them are 'superior' to most other people - Nine is supersmart, while Kei has superhuman abilities.
- There are terrorists/weapons/riots/bombs and stuff.
- Both anime contain violence, blood, murder.
- They have similar music.
- And they really give off a similar feel in general. Also, there are some really emotional moments.

Very rarely are whole full length TV series made in full 3D like these two shows are.
The atmosphere/genre/style/setting/plot/characters are all very different but the 3D visuals make them interesting curiosities.

What does it mean to be human? What separates man from monster? These are questions both Shiki and Ajin explore. With a battle between mortals and immortals, they show the points of view from both sides, and execute it well. Both series greatly deal with the darkness within humanity, and if the "monsters" really are in the wrong.

In both shows the main character discovers he's immortal and has to flee or else they'd become the subject of some cruel experiments. I recommend it one way because Pupa's plot doesn't make sense, while Ajin's storyline is coherent and engaging. so if you liked Pupa go ahead and give Ajin a try.

What makes the two series alike is that only a certain number of people posses something the majority does not have. In Mirrai Nikki it's the phones that the character in the show posses and the ability to know the outcome of future events. For Ajin, some characters posses immortality. While Mirrai Nikki's "God" literally gives a handful of people a survival game, for Ajin it is just survival and no "wish" would be granted to any of the characters ( although one or two of the characters in the anime make it seem like it is a game ).Furthermore both anime series makes you have a sense of uncertainty for the characters' personality and who the main character should really trust.&nbspread more
